Definitions
- the invention relates to an artificial acetabular cup, consisting of a rotationally symmetrical socket body made of plastic, which contains the actual socket shell, and a metal grid which is anchored in the outer surface of the socket body.
- the object of the invention is to improve this primary fixation of the socket described above and to provide an elastic connection of the mesh-reinforced socket to the bone.
- This object is achieved according to the invention in that the metal grid is symmetrical to a meridian plane of the pan shell and pan body a plurality of tabs protruding from the equatorial edge are present, which can be permanently deformed intraoperatively and at least partially have through holes for bone screws or nails.
- the tabs which can be deformed intraoperatively or also partially detached, it is possible to fix the cup with nails and / or screws directly during implantation in the pelvic bone, the fact that the tabs are part of the mesh, the elastic Deformability of the pan is not unduly impaired.
- the tabs can have different radial lengths and / or several through bores lying one behind the other in the radial direction.
- the hemispherical acetabular cup 1 receiving the joint head (not shown) of a femoral head prosthesis is located in a socket body 2 made of plastic, for example made of polyethylene.
- Pan shell 1 and pan body 2 are rotationally symmetrical to the pan axis 3 (FIG. 2).
- Holes 4 run through the socket body 2, through which bone screws or nails can be driven into the pelvic bones.
- a metal grid in the form of a multi-layer wire mesh 5 is applied to the outer surface of the socket body 2 as a reinforcing element which also serves to anchor the socket in the pelvic bone.
- Pan body 2 and wire mesh 5 are firmly connected to one another in that the innermost layer of mesh 5 is pressed into the plastic of pan body 2.
- this network 5 has a plurality of tabs 6 and 8 on its equatorial edge, some of which are also provided with bores 7.
- the thickness d (FIG. 2) of the net 5 or the tabs 6 and 8 is selected such that it remains permanently deformed intraoperatively and is adapted to the contact surface on the pelvic bone, and part of them can be separated off without effort.
- the tabs 6 and 8 - and the holes 4 in the Pan body 2 - distributed symmetrically to a plane 9 through the pan axis 3 on the edge of the pan or the net 5.
- the new cup can not only be used for cementless implantations, but can also be used in conjunction with bone cement, creating a mechanical "interlocking" between the metal grid and the bone cement.

Abstract
Description
- Die Erfindung betrifft eine künstliche Hüftgelenkspfanne, bestehend aus einem aus Kunststoff gefertigten rotationssymmetrischen Pfannenkörper, der die eigentliche Pfannenschale enthält, und aus einem Metallgitter, das in der äusseren Oberfläche des Pfannenkörpers verankert ist.
- Eine Hüftgelenkspfanne der vorstehend genannten Art ist bereits vorgeschlagen worden (CH-Anmeldung OO328/85-8). Bei dieser Pfanne ist in die Aussenfläche eines Kunststoffpfannenkörpers ein mehrlagiges Drahtnetz eingepresst, wobei eine Lage des Netzes zur innigen Verbindung beider in den Kunststoff eingebettet ist. In die restlichen Lagen des Netzes, die eine poröse "Aussenhaut" der Pfanne bilden, soll zur dauerhaften Verankerung im Knochen Gewebe einwachsen. Bevor die dauerhafte Verankerung durch einwachsendes Gewebe erfolgt, wird bei dieser Pfanne die Primärfixierung dadurch erzeugt, dass die Pfanne im Beckenknochen unter einer Vorspannung steht (CH-Anmeldung O3O65/85).
- Aufgabe der Erfindung ist es, diese Primärfixierung der vorstehend beschriebenen Pfanne zu verbessern und eine elastische Verbindung der netzverstärkten Pfanne mit dem Knochen zu schaffen. Diese Aufgabe wird nach der Erfindung dadurch gelöst, dass an dem Metallgitter symmetrisch zu einer Meridianebene von Pfannenschale und Pfannenkörper eine Vielzahl von aus dem äquatorialen Rand hervorstehenden Laschen vorhanden ist, die intraoperativ bleibend verformbar sind und mindestens zum Teil Durchtrittsbohrungen für Knochenschrauben oder -nägel aufweisen.
- Mit Hilfe der Laschen, die intraoperativ verformt oder auch teilweise abgetrennt werden können, ist es möglich, die Pfanne direkt bei der Implantation im Beckenknochen mit Nägeln und/oder Schrauben zu fixieren, wobei dadurch, dass die Laschen ein Teil des Netzes sind, die elastische Verformbarkeit der Pfanne nicht unzulässig beeinträchtigt wird.
- Infolge des symmetrischen Aufbaues und der intraoperativen "Abtrennbarkeit" einzelner Laschen ist es möglich, den gleichen Pfannentyp für rechte und für linke Gelenke zu verwenden, und auch Anforderungen hinsichtlich unterschiedlicher örtlicher "Einsatz"-Punkte und -richtungen für die Schrauben oder Nägel zu entsprechen. Daher resultiert aus diesen beiden Eigenschaften eine erhebliche Vereinfachung für die Fabrikation und die Lagerhaltung. Weiterhin können dadurch die örtlichen Fixierungspunkte im Beckenknochen relativ frei gewählt werden.
- Dies ist besonders wichtig für sogenannte "Reoperations"-Pfannen, die bei Reoperationen dazu dienen, eine andere, früher eingesetzte künstliche Hüftgelenkspfanne zu ersetzen. Besonders im Hinblick auf den Reoperationsfall können die Laschen unterschiedliche radiale Längen und/oder mehrere, in radialer Richtung hintereinander liegende Durchtrittsbohrungen haben.
- Im folgenden wird die Erfindung anhand eines Ausführungsbeispiels im Zusammenhang mit der Zeichnung näher beschrieben.
- Fig. l zeigt schematisch eine Aufsicht auf die neue Pfanne in Richtung der Pfannenachse, während
- Fig. 2 eine Seitenansicht widergibt.
- Die den nicht gezeigten Gelenkkopf einer Femurkopfprothese aufnehmende halbkugelförmige Pfannenschale l befindet sich in einem Pfannenkörper 2 aus Kunststoff, beispielsweise aus Polyäthylen. Pfannenschale l und Pfannenkörper 2 sind rotationssymmetrisch zur Pfannenachse 3(Fig. 2) ausgebildet. Durch den Pfannenkörper 2 verlaufen Bohrungen 4, durch die Knochenschrauben oder Nägel in den Beckenknochen eingetrieben werden können.
- Auf die Aussenfläche des Pfannenkörpers 2 ist als Verstärkungselement, das zugleich zur Verankerung der Pfanne im Beckenknochen dient, ein Metallgitter in Form eines mehrlagigen Drahtnetzes 5 aufgebracht. Pfannenkörper 2 und Drahtnetz 5 sind dadurch fest miteinander verbunden, dass die innerste Lage des Netzes 5 in den Kunststoff des Pfannenkörpers 2 eingepresst ist. Erfindungsgemäss weist dieses Netz 5 an seinem äquatorialen Rand eine Vielzahl Laschen 6 und 8 auf, die teilweise ebenfalls mit Bohrungen 7 versehen sind. Die Dicke d (Fig. 2) des Netzes 5 bzw. der Laschen 6 und 8 ist so gewählt, dass sie intraoperativ bleibend verformt und an die Auflagefläche auf dem Beckenknochen angepasst sowie ein Teil von ihnen ohne Mühe abgetrennt werden können.
- Um eine Verwendung der gleichen Pfanne sowohl in der linken als auch in der rechten Hüfte zu ermöglichen, sind die Laschen 6 und 8 - sowie die Bohrungen 4 im Pfannenkörper 2 - symmetrisch zu einer Ebene 9 durch die Pfannenachse 3 auf dem Rand der Pfanne bzw. des Netzes 5 verteilt.
- Selbstverständlich kann die neue Pfanne nicht nur für zementfreie Implantationen dienen, sondern auch in Verbindung mit Knochenzement verwendet werden, wobei eine mechanische "Verzahnung" zwischen dem Metallgitter und dem Knochenzement entsteht.
